“Choose some other files: Something went wrong and we couldn’t add some files” Error on Video Editor/Photos app (Windows 10)

To whom it may concern, For some reason now, I keep getting this error while trying to drag a .mp4 file into the Video Editor/Photos app in Windows 10. I have looked for solutions. I only found one that I can import a video from collections, but I want to be able to browse my computer and select the video normally like it used to and should. I have tried reseting/repairing and unintalling (Using Windows Powershell) and reintalling it. None of those solutions fixed the issue. I would apprecieate any help!Warmly, Chris
